The most severe earthquake to affect Southern California in almost 20 years erupted at 3:40 p.m. today on a poorly understood fault below the U.S.-Mexico border, 19 miles southeast of Mexicali, producing prolonged shaking that was felt by at least 10 million people across at least three states, including residents 270 miles to the northwest in Orange County, where brief, isolated power outages were reported.
